Application filed February To all whom it may concern:

Be it known that I, PERRY S. BAUER, a citizen of the United States,residing at Chicago, in the county of Cook and State of llllinois, haveinvented new and useful Improvements in Fuinigators, of which thefollowing is a specification..

rlhis invention relates to'fumigators and tudinal sectional view of afumigator taken composition lar 4bead or rib 12 lar view showing thedevice ready for use;

and Fig. `3 isa sectional elevation on .thev

line 3 3 of Fig. 2.

Referring to the drawings 5 designates a shell preferably cylindrical inforni and vcomposed of sheet-metal or other non-combustible material. Areceptacle or container 6 is fitted within one of the open ends of .theshell, an integral rib 7 being provided on theiw'all of the shell toprevent the container from slipping too far into the shell, and adaptedto contain a charge 8 of volatile vdisinfecting material in solid form.The

be composed of any preferred but preferably consists of a of solidcharacter which, when heated, will give oif formaldehyde vapor.

A cap 9 adapted to fit the end of the shell containing the charge ofdisinfectant contains a mass or charge 1() of solid hydrocarcharge maydisinfectant bon such as paraffin and a wick 11 embedded in the charge',said wick being preferably formed of paper or other combustibleinaterial which will initiate the combustion of the charge of paraffin.An internal annuis provided in the cap to prevent the charge waved.Similar of combustible materialv from, dropping out. when the cap is.rev-yf."

in the container to insure the retention of the charge ofdisinfectingmaterial, if desired.

It will be observed from Fig. l tha-t the cap fits tightly over the endof vthe disinfect-ant container and while the rib 13 limitsthetelescoping ymovement of the capon the shell it permits the edges 14of the receptacle and shell to enter the paraiiiii contained in the capsuiiiciently to form an air-tight \seal for the container. Theadvantages of this hermetic sealing ofthe container willv be obviouswhen it is remembered that the charge consists of a very volatiledisinfectant which would be vaporized and lost to 'the atmosphere long'before the device was ever used if no effective sealing were provided.`The device is marketed with the charges of disinfectant and combustibleinaterial already" disposed in the container and the cap, respectively,and the cap being aiiiXed to the shell? as shown in Fig. 1, the articlemay be shipped, handled and eX posed without Vdanger of injury toIeither of the contained charges and Without the liability orpossibility of the disinfectant becoming vaporized prior to lthe removal-of the cap.

When the-article is to be used the cap is removed from the container endof the shell and is applied to the opposite end, as shown in Fig. 2. Inthis.po'sition of the parts the bottoni of the container constitutes acrownsheet which is exposed to the heat generated in the combustionchamber formed by the portion ofthe shell below the container 6. Thecharge of ooiiibustiblel material may now be ignited by applying. aflame to the wick, sufficient oxygen being supplied to the cornbustionchamber through the perforations 15 to properly support the combustion.The heat generated in the combustion chamber lcauses the charge 8 togive oif formaldehyde vapor which escapes from the open top of thecontainer to the room to vbe disinfected. The charges of vaporizable andcombustible material are preferably so proportioned thatthey will beconsumed simultaneously, leaving only the non-combustible metallic partswhich, being of comparatively inexpensive construction, may be discardedafter the device has been used. s

.The edges of the end of the-shell opposite 'the .container arepreferably'rolled inwardly ioo los,

at 16to present a smooth surface and obviate the liability of any onecutting themselves in handling the article.

Various changes yin the size, shape and proportion ofthe various partsshown and described may be made, as will be apparent, without departingfrom the spirit of the invention.

I claim:

l. A fumigat-or comprising a shell, a disinfectant container carriedthereby, and a cap containing a Wick and a charge of combustiblematerial normally forming a seal for said container, said cap beingadapted to be disposed beneath the container for vaporizing thedisinfectant therein.

2. A fumigator comprising a shell, a receptacle containing a charge ofviolatile disinfectantsituated near one end of the shell,

a cap\ containing a Wick and a charge of combust'ble material adapted tofit over 1 either end of said shell'to form a seal for the disinfectantreceptacle and to supply heat to saidreceptacle to vaporize saiddisinfectant, respectively.

3. A fumigator comprising a shell provided at one end With an open topreceptacle containing a charge of volatile. disinfectant, and 'a capvcontaining a Wick and a charge of solid combustible material adapted tofit each end of the shell to form a seal for the disinfectantlreceptacle and to subsequently serve as a 'burner to heat saidreceptacle and Vaporize the disinfect-ant contained therein.

4. A fumigator comprising a shell, a disinfectant receptacle arrangedwithin said shell adjacent one end thereof and containing a charge ofvolatile disinfecting material, and a cap containing a Wick and a chargeof combustible material in solid form adapted to tit both ends of saidshell, said cap when fitted upon one end forming a seal for thedisinfectant receptacle and when fitted over the other end serving as aburner toheat saidreceptacle and volatilize the dis infectant containedtherein.

5. A fumigator comprising a shell carrying a charge ofl disinfectingmaterial, and a cap containing a Wick and a combustible chargeconsisting of a body of solidified hydrocarbon, said cap being adaptedto Iit either end of the shell, the end of the shell being embedded inthe hydrocarbon. when the cap is disposed over one end of the'shellthereby forming a hermetic seal for the dis infectant contained in theshell, the cap.

when fitted upoli the opposite -end of lthe shell serving as a burner toheat the disinfectant and cause the same to be volatilized. G. Afumigator comprising a shell having a charge of disinfecting material,and a cap carrying a charge of combustible material and a Wick, said capbeing adapted to lit one end of the shell to form a seal for saiddisinfecting material and to be detached therefrom and positionedbeneath .the other end rof the shell for vaporizing said disinfectingmaterial.
